Types of Computer Network

 



Computer networks are systems that allow multiple computers to communicate and share resources with each other. There are several types of computer networks, each with their own characteristics, advantages, and disadvantages. 


1. Local Area Network (LAN): A LAN is a type of network that connects computers within a limited geographical area, such as a school, office, or building. LANs are often used to share files, printers, and other resources between computers. 


2. Wide Area Network (WAN): A WAN is a network that connects computers over a large geographical area, such as multiple cities or countries. WANs are often used to connect different branch offices of a company or to connect a company's network to the Internet. 


3. Metropolitan Area Network (MAN): A MAN is a network that covers a larger area than a LAN but a smaller area than a WAN. MANs are often used to connect multiple LANs within a city or town. 


4. Wireless Network: A wireless network uses radio waves or infrared signals to connect devices to a network without the need for physical cables. Wireless networks are commonly used in homes and offices to connect laptops, smartphones, and other mobile devices to the Internet. 


5. Client-Server Network: In a client-server network, one or more computers (servers) provide services or resources to other computers (clients) on the network. Examples of client-server networks include web servers that provide websites and email servers that provide email services. 


6. Peer-to-Peer Network: In a peer-to-peer network, all computers on the network have equal status and can share resources and services with each other. Peer-to-peer networks are often used for file sharing, such as BitTorrent or other peer-to-peer file sharing systems. 


7. Virtual Private Network (VPN): A VPN is a network that allows users to connect to a private network over the Internet. VPNs are commonly used to provide remote access to company networks or to protect online privacy by encrypting Internet traffic. 


Each type of network has its own advantages and disadvantages depending on the needs of the users. It's important to choose the right type of network to ensure that the network can meet the needs of the users.

EDI is widely used in many industries such as retail, healthcare, finance, and manufacturing, where there is a need to exchange large volumes of standardized business documents between trading partners. EDI helps to streamline business processes, reduce costs, improve accuracy, and increase efficiency in the supply chain. EDI works by using a set of standardized message formats such as EDIFACT or ANSI X12 to exchange data between computer systems. The data is exchanged over a secure network using a variety of communication protocols such as FTP, AS2, or VAN. EDI software is used to translate the data into t...
